Can't installer .net 3.5 on Windows 10
Re: Can't installer .net 3.5 on Windows 10
Please open a invite de commandes (cmd.exe) en tant qu'administrateur and run la commande suivante to install .Net 3.5:
```
DISM /Online /Enable-Feature /FeatureName:NetFx3 /Source:d:\sources\sxs /All /LimitAccess
```
(replace D: with your mounted Win10 ISO)
In some environment, DISM fails to fetch the file (Proxy, network policies). The DISM command takes the files from the DVD and you're fine.
Si vous êtes MSDN subscriber vous pouvez aussi download the `Windows 10 Features on Demand` ISO, mount the ISO, copy the Microsoft-Windows-NetFx3-OnDemand-Package.cab to C:\Features (or a different folder) and those commands:
```
DISM.EXE /Online /Add-Capability /CapabilityName:NetFx3~~~~ /Source:C:\Features
```
If this fails, run this:
```
DISM.EXE /Online /Add-Package /PackagePath:C:\Features\Microsoft-Windows-NetFx3-OnDemand-Package.cab
```
```
DISM /Online /Enable-Feature /FeatureName:NetFx3 /Source:d:\sources\sxs /All /LimitAccess
```
